Abstract: Two step driving technique is used to turn on the power switch of a power management apparatus in such a manner that the power switch is weakly turned on first and then goes into a low ON-resistance region. The power switch is so avoided to operate at highest gate and drain voltages simultaneously even a non-uniform turn on happens, and is thereby away from avalanche breakdown. The safe operation region of the power management apparatus is therefore extended with minimum efficiency degradation.

Abstract: A single-chip common-drain JFET device comprises a drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation.

Abstract: Electronic circuits use low-cost depletion-mode JFET to serve as power switch. Since depletion-mode JFET has smaller conductive resistance and is majority carrier device, the energy loss is less when current flows through the depletion-mode JFET, and faster switching speed is obtained, thereby enhancing the efficiency of the electronic circuits.
